This is an unofficial implementation of jReadability's algorithm in JavaScript, adapted from @joshdavham's implementation in Python.

The Japanese text readability measurement system 'jReadability' (https://jreadability.net) is developed under Grants-in-Aid for Scientific Research (KAKEN) 25370573. Please refer to their website for more information: https://jreadability.net/

Example usage

import jReadability from "jreadability";
const analyzer = new jReadability.Analyzer("/path/to/unidic/dictionary/folder");
